I started at this small software company (approx 100 people) about 2 years ago. I'm pretty early on into my career and I started as a base software engineer.
About 6 months ago, my manager left the company. I was given more responsibility and called a "tech lead." I basically ran the schedules and lead the work but didn't get a raise or official title change. I absorbed a big chunk of the responsibility of my manager who left. I was managed by someone else who took over the team.
Then, 1.5 months ago, I was promoted one level up to a senior engineer, after the review cycle concluded. I received a raise of 7.5%. I was told this was a result of my good work leading the small team in development.
Now, 1.5 months later, a manager position opened up (there was some reorganization and someone left) and my boss' boss wants to know if I want to take it. He says my title will change to "software development manager" but otherwise nothing else will change at this time. I'll have 7 people reporting to me. He says the position is on the same level as the one I just received 1.5 months ago and that this is a lateral move to a parallel management track. The emphasis was on what a great opportunity this is for me and how much confidence the company has in me.
I do want this, I've honestly felt like I've taken naturally to leading a team and I can't wait for it to be more officially recognized and to have direct reports. However, it feels like I should get another raise or some title that isn't at the "same level" as senior engineer, which is what I just received. My boss' boss who is offering this says that it's normal for this to be a lateral move and not a seniority or pay jump at this time. In addition, I feel awkward asking for more since I just received a raise and a title bump.
Is this normal? Should I be negotiating this further? He said that if I want I can turn it down and they'll hire someone from outside to do the job, but I only have one day to decide. I just feel like it's not fair to get more respnosibility without more pay, but the timing is awkward right after the previous raise. I'm also afraid they could take it away and just hire someone else. Should I ask for more?
